Local dimming of backlights achieves high contrast ratio and low power consumption for LCDs. However, it induces flicker artifacts. The moving average filtering method effectively reduces the flicker artifacts, but causes another problem known as backlight‐response‐time delaying. This paper presents an adaptive moving average filtering method to deal with above problems. Experimental results show that the proposed method successfully reduces flickers without backlight‐response‐time‐delaying.
